Did we just get our explanation on last season finale's biggest mystery?

I am talking about Jack's comment about his father being alive.

The way I am seeing it now is that Charlie is to Hurley as Christian is to Jack.

There is a pattern emerging...


It seems that all of the Oceanic Six will go through the same 'going nuts' process. Hurley was the first one. Jack will probably go next.
Once all six of them have realized that they HAVE to go back. The Ferryman will take them back.
And who is the Ferryman?

Mathew Abaddon.

He is also responsible for these visions which only purpose is to help them realize that they shouldn't have left the island. The island is manipulating them into thinking that they have a reason to go back.
